Jordan Spieth, who dropped four strokes in the final four holes to finish one over on Thursday, was surging up the leaderboard among the day's later starters, who were playing in much drier conditions.

The defending champion made birdies at the third, fifth, 10th and 11th to sit three under for the tournament.

Tony Finau was one stroke off the leaders, alongside Tommy Fleetwood who was among the early finishers.
